Windows Internet Explorer 9 has more support for Cascading Style Sheets (CSS) than any previous version of Windows Internet Explorer. Continuing on the work to enhance CSS support that was done in Windows Internet Explorer 8—where Internet Explorer became fully compliant with the Cascading Style Sheets, Level 2 Revision 1 (CSS2.1) specification—Internet Explorer 9 adds support for many components of Cascading Style Sheets, Level 3 (CSS3).

Note  It is important to remember that many CSS3 modules are still in the Working Draft or Last Call stages. Until they reach the Candidate Recommendation stage, they could change significantly. For more information, see the latest CSS3 draft modules.


This section of the Internet Explorer 9 Developer Content contains several tutorials that teach you how to take advantage of many of the newly supported CSS3 features in Internet Explorer 9.
